Abstract:

Today, there is a shift towards a positional candidate approach in the
molecular identification of genes. This study reports on an Expressed
Sequence Tags (ESTs) mapping initiative in goats, based on sequence
information gathered from a previous mammary gland cDNA systematic
sequencing project. A total of 25 novel genes was localised cytogenetically
on 16 goat chromosomes. Six of these ESTs were found to map to cattle
milk QTL regions. These results made it possible to assess the use of
ESTs as a shortcut to the molecular identification of some QTLs and as
a valuable tool for comparative mapping.
